This article reports on pharmacognostic evaluation or standardization of the crude drug powder of Albizia odoratissima bark powder. Albizia odoratissima bark powder has been standardized on the basis of organoleptic properties, physical characteristics, and physico‐chemical properties and phytochemical investigation. In the phytochemical investigation flavonoids, tannin, carbohydrate, saponin, triterpenoids are found to be present.

Despite variation of species diversity was found in different saline zones the highest numbers of species were recorded in moderately saline zone. Distribution of existing plant species were recorded as 67.20% trees and 32.80% were woody, non-woody and climber types. The family Euphorbiaceae followed by Poaceae and Fabaceae represented highest number of species. On an average, 181 species existed per homestead. Distribution of species in different saline zones varied and it was highest in less saline zone (37.16%) followed by strongly saline (32.55%), and moderately saline (30.29%) zones. The most prevalent timber tree species are Albizia richardiana, Swietenia macrophylla and Samanea saman. Adaptation of different species in various saline zones widely varied due to different levels of salinity while Cocos nucifera as fruit species was almost equally dominant in all saline zones.

  • Medicinally Important Aromatic Plants with Radioprotective Activity

Looking into natural resources, particularly products of plant origin, has become an exciting area of research in drug discovery and development. Aromatic plants are mainly exploited for essential oil extraction for applications in industries, for example, in cosmetics, flavoring and fragrance, spices, pesticides, repellents and herbal beverages. Although several medicinal plants have been studied to treat various conventional ailments only a handful studies are available on aromatic plants, especially for radioprotection. Many plant extracts have been reported to contain antioxidants that scavenge free radicals produced due to radiation exposure, thus imparting radioprotective efficacy. The present review focuses on a subset of medicinally important aromatic plants with radioprotective activity. Lay abstract: Aromatic plants have been used as natural medicines since prehistoric times. They are cur- rently mainly utilized for essential oil extraction and are widely used in cosmetics, flavoring and fragrance, spices, pesticides, repellent and herbal beverages.

  • Prevalence of Mistletoes in Fruit and Timber Trees in the Wet and Intermediate Zone of Sri Lanka
    Tropical Agricultural Research Vol. 29 (4): 430 – 440 (2018) Short Communication Prevalence of Mistletoes in Fruit and Timber Trees in the Wet and Intermediate Zone of Sri Lanka S.S. Yapa, A.J. Mohotti1*, M.A.P.K. Seneviratne, B.L. Peiris1 and K.U. Tennakoon2 Postgraduate Institute of Agriculture University of Peradeniya Sri Lanka ABSTRACT: A survey was conducted to identify the parasitic plant species occurring in timber and fruit trees during November 2015 to April 2017, in 15 Districts of Wet and Intermediate Zones of Sri Lanka using two stage stratified random sampling scheme. The parasitic plants on fruit and timber trees were identified by comparing them with the specimen in National Herbarium, Peradeniya. Host plant species were taxonomically identified after consultation of botanical experts and using species identification keys. Correlation between parameters were made using SAS software. Mistletoes infested in varying degrees in 27 perennial fruit and 20 timber tree species in different cropping systems. Dendrophthoe falcata, D. neilgherrensis, Scurrulla cordifolia, Viscum articulatum, Taxillus incanus, and V. orientale were the mistletoes species infested in fruit trees; whereas, D. falcata, D. neilgherrensis, S. cordifolia, S. parasitica, V. articulatum and V. orientale were found in timber species. D. falcata was the most predominent parasitic plant in both fruit and timber trees. Mangifera indica and Albizia odoratissima were the most susceptible host fruit and timber species, respectively. The study indicated that further studies are required on the increased occurrence of parasitic plants, their effects on host plants and development of control measures. Keywords: Parasitic plants, mistletoes, host plants, timber, fruit trees INTRODUCTION Parasitic plants are angiosperms that meet their water and food requirements by exploiting their host plants with exquisite adaptations.

Abstract Bhindawas Wetland is spread over an area of 1074 acres in Jhajjar district of Haryana State, India. Bhindawas wetland in present time encountered with various environmental problems viz., point and non-point pollution created by surrounding agricultural fields and from drain No. 8, weed infestation, eutrophication and siltation etc. Water logging of peripheral agricultural field with higher salinity is threat to biodiversity loss. Keeping in view of biodiversity losses in the wetland, the present study was carried out to generate documentation information regarding floral and avian faunal diversity of Bhindawas wetland. Plants and birds were identified by comparing the specimen of plants with existing herbarium and picture of material prescribed in good reference books and with the help of expert. A total of 84 plants species have been reported. The maximum numbers of plant species were belonged to order Fabales followed by order Lamiales family. Total of 66 species of wetland birds belonging to 30 families have been recorded from the study area. Of all, families Anatidae dominated the list with 9 species.

  • 1 Prospect of Natural Regeneration of Tree
    DOI: https://doi.org/10.3329/jbcbm.v5i2.44909 J. biodivers. conserv. bioresour. manag. 5(2), 2019 PROSPECT OF NATURAL REGENERATION OF TREE SPECIES IN HAZARIKHIL WILDLIFE SANCTUARY OF CHATTOGRAM, BANGLADESH Rahman, M. A., M. A. Alim, M. K. Hossain and M. A. Hossain Institute of Forestry and Environmental Sciences, Chittagong University, Chattogram-4331, Bangladesh Abstract Natural regeneration of tree species is the major means of understanding the restoration potentiality of a secondary forest. Natural regeneration of a forest is a tool for measuring the health of the forest ecosystem. Natural regeneration status of tree species in Hazarikhil Wildlife Sanctuary (HWS) in Chittagong North Forest Division, Bangladesh was assessed laying 75 systematic quadrats of 4m×4m in size. A total of 90 regenerating tree species belonging to 34 families was identified from the HWS. Euphorbiaceae family possessed maximum regenerating tree species (14 species) followed by Mimosaceae (7), Lauraceae and Meliaceae (6 species each), and Moraceae (5 species). The overall seedling density was 7,083 per ha where Ficus hispida showed the highest number of seedlings (792 per ha) followed by Quercus sp. (475), Ficus religiosa (408), Lithocarpus elegans (375) and Lepisanthes rubiginosa (367). The number of Ficus hispida seedlings per ha was higher due to high coppicing ability. Lepisanthes rubiginosa attained maximum IVI (27.59) followed by Ficus hispida (21.18) and Quercus oxyodon (13.32). The seedlings of Aegle marmelos, Lithocarpus sp., Flacourtia jangomas, Albizia odoratissima, Acronychia padunculata, Chaetocarpus castanicarpus, Maesa paniculata, Crypteronia paniculata, Streblus asper and Mussaenda roxburghii were also found common in the study area. The findings will create baseline information of regenerating tree species, composition, diversity and population structure which can be used for monitoring future changes as well as taking policy decisions for the management of this Wildlife Sanctuary.

ABSTRACT Various traditional systems of medicine enlightened the importance of the leaves of Albizia odoratissima (L.F) benth (Mimosoideae) to have a great medicinal value. The present study was aimed at pharmacognostic and preliminary phytochemical evaluations of A.odoratissima leaves. The pharmacognostic investigations were carried out in terms of organoleptic, macroscopy, microscopic and physical parameters. The dried leaves powder was subjected to successive Soxhlet extraction using petroleum ether, chloroform, ethyl acetate, methanol, ethanol and water. These solvent extracts were subjected to a preliminary phytochemical screening to detect the different chemical principles present viz., carbohydrates, proteins, amino acids, steroids,
